YB26SKW01-FB

Pushbutton Switches

A pushbutton switch is a device used to quickly de-energize or re-energize an electrical circuit. Pushbutton switches are found in a variety of applications, ranging from home appliances to industrial machinery. Pushbutton switches are designed to be easy to operate and are often mounted on a plastic or metal housing.

YB26SKW01-FB application field and working principle

The YB26SKW01-FB is a high quality single pole momentary pushbutton switch. It is ideal for applications requiring consistent response time, high reliability and low cost. The switch is available in six action types: normally open, normally closed (SPST), normally open and normally closed (SPDT), normally closed with delayed action, normally open and normally closed with delayed action (SPDT/DA) and alternate action (SPDT/AA).

The YB26SKW01-FB provides reliable connections and a high-level of user convenience with its actuation force of 500 g, operating force of 400 g and total travel of 1.2 mm. It features a rating of 1.8 A at 125 Vac/30 Vdc, 100,000 cycles mechanical life, a contact resistance of 50 mω and an insulation resistance of greater than 1,000 Mω. Its operating temperature range is -20°C to +85°C and it is IP67 rated for dust and moisture protection.

The YB26SKW01-FB is constructed with a silver alloy contact and has ground terminals for improved EMC performance. Its pushbutton head is made of a PA66/GF material with an integrated LED illumination. The leg terminals are made of brass with a tin-plated finish, which provides improved corrosion resistance.

The working principle of the YB26SKW01-FB is relatively simple. When the pushbutton is pressed, the normally open or normally closed contacts inside the switch close or open, thus controlling the circuit power. When the pushbutton is released, the contacts return to their original positions and the circuit is reverted to its original state.

In summary, the YB26SKW01-FB is an excellent choice for applications requiring a reliable, low-cost, and easy-to-use pushbutton switch. Its wide range of action types, robust construction, and efficient design make it one of the best pushbutton switches on the market.
